A network controller design and dynamic scheduling method based on switched principle is proposed for networked control systems with limited channel resource and quantizer. Considering the influence of medium access constraints

a communication constrained networked control system is transformed into a non-uniformly sampled switched system with multiple subsystems by using the switching scheduling matrix. By using Lyapunov stability theory to derive sufficient conditions for robust stabilization of the system

the design can meet the arbitrary switching stable robust controller and optimal dynamic scheduler. Finally

a simulation example is given to illustrate the effectiveness of the proposed method.
